“The secondary was on fire,” Tatupu said. “We’re getting a good rush out of the front and good communication by the linebackers, but the secondary came out today and they weren’t going to be denied.”

PLAYS OF THE DAY
Offense: Rookie tight end John Carlson was able to catch a Hasselbeck pass even though it Tatupu tipped it, and Hasselbeck had time to make the throw because running back Julius Jones picked up a blitzer.

Defense: On Jennings’ interception, Tatupu first knocked wide receiver Nate Burleson off his route – setting up the pick – and then stopped 254-pound running back T.J. Duckett in his tracks with a solid shot on Jennings’ return.

Grant saluted the double-play by hollering, “Oh yeah, Lofa.”

UNIT WATCH
Zebra. No, the officials who worked Saturday’s scrimmage were not back at practice. This is what the Seahawks call their three wide receiver/tight end/one back package.

This morning, the No. 1 unit included Burleson and Ben Obomanu outside, Bobby Engram in the slot, Carlson at tight end and Jones at running back.

The No. 2 unit was comprised of Jordan Kent and Joel Filani outside, Michael Bumpus in the slot, Will Heller at tight end and Maurice Morris at running back.

Some shuffling was required because wide receiver Courtney Taylor remains limited after missing time with a tight hamstring and wide receiver Logan Payne is out. Taylor had been working with Burleson and Engram in the No. 1 group, and Payne in the No. 2 group with Kent and Obomanu.

INJURY REPORT
The big news, of course, was veteran offensive lineman Chris Gray announcing his retirement because of a lower back injury that could led to paralysis if he attempted to continue playing.

Defensive tackle Kevin Brown was signed to fill Gray’s roster spot.

Tight end Jeb Putzier and tackle Kyle Williams returned to practice after missing time with hip and knee injuries, respectively.
